Definitions
- the present invention relates to a method of hot-shaping from a sheetmetal blank and hardening a sheetmetal object in a cooled tool, at which there is double sheetmetal in part of the blank and the whole blank is shaped in a single forming operation.
- the invention also relates to a B-pillar for a vehicle.
- An object of the invention is to provide greater possibilities for choosing freely different characteristics in different portions of a shaped product and to make it easy to achieve different degrees of hardness in different portions of a product formed from a planar sheet steel blank.
- Fig. l is a perspective view of a B-pillar for a vehicle depicted by way of example of the invention, showing the pillar as seen from outside the vehicle.
- Fig. 2 is a perspective view of the B-pillar as seen from inside the vehicle.
- Fig. 3 is a cross-section along the line 3-3 in Fig. 1.
- Fig. 4 is a perspective view of the blank from which the B-pillar in the above drawings is formed.
- Figs. 1-3 depict by way of example a B-pillar which comprises a hat beam section 11 and a cover 12.
- the hat beam section is enlarged upwards and downwards to form transverse hat sections 13,14 which are intended to be fastened to the vehicle in order to constitute a load-bearing element of the vehicle.
- the hat beam section 11 has a central flange 15, two webs 16,17 and two side flanges 18,19.
- Fig. 4 depicts the sheet steel blank from which the hat beam section 11 is shaped. It comprises two blank elements 20,21 placed overlapping.
- Fig. 4 shows the blank element 21 which is to become the pillar's lower portion placed partly on top of the blank element 20 which is to become the upper portion of the pillar.
- the overlap portion 23 is spot- welded or stitch- welded at points distributed across the whole surface, as indicated by the crosses 24.
- the overlap edge is fully welded, i.e. both the edge 25 of the blank element 21 on top of the blank element 20, and the edge 26 of the blank element 20 under the blank element 21, thereby providing not only reinforcement but also protection against crevice corrosion.
- the edge need not necessarily be fully welded.
- the welded-together blank 20,21 is heated in a furnace to austenitising temperature and is hot-shaped in a cooled tool pair, after which it is left with the tools serving as cooling fixtures.
- This combined shaping and hardening operation is a known process called press-hardening. It is possible to adopt for the upper blank element such a steel grade that the upper portion of the pillar fully hardens and to adopt for the lower blank element a steel grade which is only partly or not at all hardenable.
- the result is a pillar comprising three portions with different strengths, with a middle portion, the overlap portion, having the greatest strength and a lower portion the least strength. The portion between the hinge fastenings thus becomes the strongest portion.
- the cover 12 is welded firmly to the hat beam's side flanges 18,19.
- Figs. 1 and 4 the side flanges constituted by the two blank elements 20,21 have a short overlap 27, whereas the remainder of the overlap portion of the blank 21 is narrower so that it forms no side flange in the overlap region.
- Fig. 3 depicts the hat beam's overlap portion and the portions constituted by the blank elements 20,21 with these reference notations.
- the upper blank element 20 is depicted in Fig. 3 on top of the lower element, but the blank 20,21 may alternatively be so formed that the lower blank element comes outermost.
- Welding the two blank elements together to form a Taylor blank may with advantage be effected by remote laser welding both for the overlap edges and for the stitching across the overlap surface.
